Operating the device in the local network (LAN)
NOTICE
Do not connect the device to a public network (e.g. the internet).
An Ethernet/IP-based network connection (LAN) is required to operate the device in a local network. In its delivery state,
the device is configured to obtain the IP address automatically from a DHCP server operated in a LAN.
NOTICE
Check the IP address carefully during the conversion for a manual configuration before connecting
the device to the LAN.
An incorrectly-entered IP address can cause IP conflicts in the network and thus disturb another device in your
network.
In the LAN with a firewall, only permit connections to and from the device which correspond to the intended use of the
device. All ports not used are blocked on the device side.
The device is able to make the following connections as standard:
